Update the Profile Badges 101 article

Although the Profile Badges 101 is a great article, it is lacking lots of information about some of the newer badges that were added, some popular examples being the Discord Certified Moderator and Early Verified Bot Developer badges.

I have compiled a list of every single badge that is missing from the article:

1. Discord Certified Moderator badge
2. Early Verified Bot Developer badge
3. Bug Buster badge (golden variant of Bug Hunter badge)
4. Supports Commands badge (newly added badge given to bots that support slash commands)
